What I'm looking for

I seek a role where I can own frontend architecture and performance initiatives, work cross-functionally, mentor engineers, and contribute to high-impact, accessible web experiences.

I am a Senior Frontend Engineer with 5+ years building scalable, high-performance React and TypeScript applications, owning features end-to-end from API integration to production deployment. I contribute to open source—creator of a Mozilla Firefox add-on and an npm package—and focus on delivering fast, measurable business impact.

I have led frontend architectures and optimizations that reduced load times and production issues, established reusable component systems, CI/CD automation, and mentored junior developers to boost team velocity. My work emphasizes performance, accessibility (WCAG), and reliable engineering practices to balance user experience and technical sustainability.
